Durable Dog Harness Kurgo Enhanced Strength Tru-Fit Smart Harness. Designed for traveling by car with your furry friend. Engineered and manufactured according to climbing harness production standards, where quality, durability, overload resistance, and safety are paramount. Kurgo car harnesses have undergone rigorous crash testing (similar to that conducted for child seats) at Calspan, Buffalo (USA) and passed laboratory testing procedures for pet safety harnesses. Dynamic crash tests were conducted in accordance with FMVSS 213 standards, developed for the protection of children, which can also be applied to dogs. The Kurgo Tru-fit Smart Harness is tailored to be not only safe but also comfortable for dogs. No adventure is too daunting. You can use them for daily walks, running with your dog, or during longer hikes. Made from sturdy materials, resistant to overload and long-term use. The front section protects the chest from pressure. The five-point adjustment allows for precise fitting to the dog's body shape. Equipped with solid metal buckles. A large carabiner allows you to attach the harness to seat belts in the car. An attached strap with a handle allows you to hold the dog, for example, when getting in or out of the car. The harness also features two D-rings for leash attachment.

Attach the carabiner to the loop located on the dorsal part of the harness.
